Description

Technical Field

[0001] This application relates to the field of wall panel prefabrication equipment technology, and in particular to an exterior wall panel prefabrication equipment for green buildings. Background Technology

[0002] Green building exterior wall panels take energy saving, environmental protection, fire resistance, durability and prefabrication as the core requirements. The mainstream types are precast concrete insulated and decorated exterior wall panels, ALC autoclaved aerated concrete exterior wall panels and composite lightweight exterior wall panels. All of them adopt the standardized factory prefabrication and on-site assembly mode.

[0003] In related technologies, a prefabricated exterior wall panel mold includes a base plate and side templates disposed opposite each other on both sides of the base plate in the width direction. End templates that fit together with the side templates are provided at both ends of the base plate in the length direction. The base plate, side templates and end templates form a rectangular frame with a top opening for filling grout and solidifying and hardening into a prefabricated exterior wall panel.

[0004] Regarding the aforementioned technologies, the inventors discovered that in the existing prefabricated building wall panel production process, the exterior wall panels tend to adhere to the mold after solidification. Conventional demolding methods often involve using a sledgehammer to strike the mold and demold through vibration. This method is not only difficult and inefficient to demold, but also prone to causing the wall panel surface to peel off or crack due to localized large impact forces, which seriously affects the product molding quality. Therefore, improvements are needed. Summary of the Invention

[0005] To address the problem of inconvenient demolding of precast wall panels, this application provides a precast exterior wall panel device for green buildings.

[0006] This application provides a prefabrication device for exterior wall panels used in green buildings, which adopts the following technical solution: A prefabrication device for exterior wall panels in green buildings includes a base plate and several sets of templates arranged around the base plate for casting the wall panel body; a workbench is arranged below the base plate, and a vibration component for uniformly vibrating the base plate is arranged on the workbench, as well as an inflation component for inflating the inner wall of the template; a movable frame is slidably arranged on the workbench, and a rinsing component for rinsing the joint between the template and the wall panel body is arranged on the movable frame, and a positioning component is arranged on the movable frame for positioning the movable frame.

[0007] By adopting the above technical solution, after the wall panel body is cast and solidified in the mold cavity formed by the base plate and the template, the vibration component first applies uniform micro-vibration to the base plate, causing loosening and micro-gaps between the wall panel body and the base plate. Then, the inflation component injects high-pressure gas into the interface between the inner wall of the template and the wall panel body, using the air film effect to initially separate the inner wall of the template from the outer wall of the wall panel body. Finally, the rinsing component sprays high-pressure water along the joint between the template and the wall panel body for rinsing. After the high-pressure water penetrates the joint, it further destroys the adhesion of the bonding interface, completing the complete separation of the wall panel body from the template. This application replaces the traditional manual knocking demolding method through the synergistic effect of three processes: vibration loosening, air pressure peeling, and water rinsing. It transforms the concentrated impact force into a uniformly distributed vibration force, air pressure, and rinsing force, effectively reducing the demolding difficulty, avoiding peeling or cracking of the wall panel surface, and improving the convenience of demolding and product quality.

[0008] Preferably, the shock-absorbing assembly includes a fixed plate, a shock-absorbing component, an anti-detachment guide rod, a force-equalizing plate, a shock-absorbing rod, and a resetting component. The fixed plate is disposed at the bottom of the workbench, and the shock-absorbing component is disposed on the fixed plate for shocking the fixed plate. The anti-detachment guide rods are spaced apart on the side wall of the fixed plate facing the workbench. The force-equalizing plate is slidably sleeved on all the anti-detachment guide rods, and the side wall of the force-equalizing plate facing away from the workbench abuts against the fixed plate. The shock-absorbing rod is disposed on the side wall of the force-equalizing plate facing the workbench, and the end of the shock-absorbing rod away from the force-equalizing plate penetrates the workbench for shocking the bottom plate. The resetting component is disposed on the anti-detachment guide rod to drive the force-equalizing plate toward the fixed plate and reset it through its own elastic force.

[0009] By employing the above technical solution, the vibration-damping component generates high-frequency vibration force that acts on the fixed plate. The fixed plate transmits the vibration to the force-equalizing plate via the anti-detachment guide rod. The force-equalizing plate then evenly distributes the vibration to each vibration-damping rod. The vibration-damping rods penetrate the worktable and act directly on the bottom surface of the base plate. Because the force-equalizing plate slides along the anti-detachment guide rod, the guide rod guides and restricts the movement direction of the force-equalizing plate, ensuring that the vibration energy is evenly transmitted to all areas of the base plate through the force-equalizing plate and the vibration-damping rods, avoiding concentrated force at a single point. The reset component pulls the force-equalizing plate back to its original position after each vibration impact, ensuring that the force-equalizing plate remains in contact with the base plate after the impact.

[0010] Preferably, the inflation assembly includes a sealing screw, a pressurizing pump, an air supply pipe, and an adjusting component; the side wall of the template has several sets of insertion holes for threaded connection of the sealing screw, and the side wall of the template has several sets of air inlets for connecting the insertion holes, with the ends of the air inlets facing the wall panel body communicating with the ends of the insertion holes facing the wall panel body; the sealing screw is threaded into the insertion hole, and the end wall of the sealing screw is coplanar with the side wall of the template to seal the connection between the insertion hole and the air inlet; the pressurizing pump is mounted on the template, and the air supply pipe is connected to the pressurizing pump to connect the air inlet; the adjusting component is mounted on the template to adjust the position of the sealing screw.

[0011] By adopting the above technical solution, during the casting and molding of the wall panel body, the end wall of the sealing screw is coplanar with the inner wall of the template, ensuring the integrity of the surface of the wall panel body after molding; the sealing screw seals the connection between the insertion hole and the air inlet, preventing slurry from entering the channel; during demolding, the adjusting component drives the sealing screw to withdraw a certain distance outward, so that the insertion hole and the air inlet are connected. The pressurized pump sends high-pressure gas into the air inlet through the air supply pipe. After the gas enters the insertion hole from the inclined air inlet port, it is blown onto the bonding interface between the inner wall of the template and the wall panel body. The high-pressure gas permeates along the interface gap to form an air film, gradually separating the inner wall of the template from the outer wall of the wall panel body.

[0012] Preferably, the adjusting component includes a fixed toothed ring, a sliding frame, an adjusting rack, and an adjusting electric cylinder; the fixed toothed ring is sleeved on the end of each set of sealing screws exposed on the template, the sliding frame is slidably disposed on the template, the adjusting rack is disposed on the sliding frame, and the adjusting rack meshes with the fixed toothed ring; the adjusting electric cylinder is disposed on the template to drive the sliding frame to move the adjusting rack relative to the fixed toothed ring.

[0013] By adopting the above technical solution, the electric cylinder drives the sliding frame to slide along the outer wall of the template. The adjusting rack on the sliding frame drives each fixed toothed ring to rotate synchronously. The fixed toothed ring drives the sealing screw to rotate. The threaded transmission makes the sealing screw withdraw outward or feed inward along the insertion hole axially. The withdrawal and feed of each sealing screw are uniformly adjusted to ensure that the airflow channel cross section of each air inlet is consistent, thus realizing convenient adjustment of the sealing state of the sealing screw to the insertion hole.

[0014] Preferably, the flushing assembly includes a lifting platform, a lifting component, a rotating arm, a rotating motor, an extension rod, a sliding block, a spray gun, and an elastic element. The lifting platform is slidably mounted on a movable frame, and the lifting component is mounted on the movable frame to drive the lifting platform closer to or away from the worktable. The rotating arm is rotatably mounted on the side wall of the lifting platform facing the worktable, and the rotating motor is mounted on the lifting platform to drive the rotating arm to rotate around the rotating motor. The extension rod is slidably inserted through the end of the rotating arm away from the rotating motor, and the sliding block is rotatably mounted on the end of the extension rod away from the rotating arm. The side wall of the lifting platform facing the worktable has a guide ring groove surrounding the perimeter of the wall panel body, and the sliding block is slidably mounted inside the guide ring groove. The spray gun is mounted on the end of the extension rod away from the rotating arm to spray high-pressure water towards the joint between the template and the wall panel body. The elastic element is mounted between the extension rod and the rotating arm to drive the extension rod and the rotating arm away from each other through its own elasticity.

[0015] By adopting the above technical solution, the rotating motor drives the rotating arm to rotate, and the sliding block at the end of the extension rod slides along the guide ring groove. The elastic force of the elastic element pushes the extension rod outward, so that the sliding block always fits tightly against the groove wall of the guide ring groove, causing the spray gun to move around the circumferential contour of the wall panel body, ensuring that the distance between the spray gun and the joint between the template and the wall panel body remains constant. The lifting component drives the lifting platform to move up and down along the moving frame, so that the spray gun can cover the joint at different heights. While the spray gun moves along the joint, it sprays high-pressure water. The water seeps into the bonding interface along the joint to wash and peel it off. The wedging effect of the water separates the template and the wall panel body, and the water can also wet the wall panel body and clean the template, which facilitates the subsequent curing of concrete.

[0016] Preferably, the positioning assembly includes a positioning rod, a positioning cylinder, and a positioning plate; the positioning rod is disposed on the worktable, the positioning cylinder is disposed at the bottom end of the movable frame, and the positioning plate is disposed at the output end of the positioning cylinder for fitting the positioning rod.

[0017] By adopting the above technical solution, after the mobile frame slides along the workbench to the preset position, the positioning cylinder drives the positioning plate to descend, and the positioning rod is inserted into the sleeve hole on the positioning plate, locking the mobile frame on the workbench to prevent the mobile frame from shifting during the washing operation.

[0018] Preferably, the workbench is provided with several sets of fixing seats for surrounding all templates at intervals around the base plate, and the fixing seats are distributed one-to-one with the templates; each template includes several sets of interlocking splicing plates, and all splicing plates are arranged sequentially along the height direction of the fixing seats; each fixing seat is provided with a locking component for limiting the movement of the splicing plates, and the fixing seat is provided with a driving component for driving the splicing plates to move sequentially towards the fixing seat in a direction that gradually moves away from the rinsing component.

[0019] By adopting the above technical solution, the template is composed of multiple sets of splicing panels sequentially spliced ​​along the height direction. During demolding, the driving component and the locking component cooperate to pull each splicing panel back towards the fixed seat layer by layer in a top-to-bottom order, so that the splicing panels gradually detach from the outer wall of the wall panel body. The layer-by-layer peeling method decomposes the adhesion force between the entire template and the wall panel body into the adhesion force between each splicing panel and the wall panel body, reducing the force required for demolding. In addition, after the upper splicing panel detaches from the wall panel body, the water accumulated inside the mold flows out, exposing the joint between the lower splicing panel and the wall panel body. This allows the rinsing component to directly rinse the joint between the lower splicing panel and the wall panel body, improving the rinsing effect of the rinsing component on the lower splicing panel and the separation effect of the wall panel body. It also reduces the phenomenon of the wall panel body being difficult to rinse when it is deeply embedded in the mold, ensuring that all parts of the wall panel body receive rinsing and curing effects, and further improving the quality of the wall panel body.

[0020] Preferably, the locking assembly includes a sliding rod, a limiting plate, a linkage plate, a locking block, and a locking cylinder; the sliding rod is slidably mounted on the fixed base, and the sliding rod is distributed at both ends of each set of splicing plates; the limiting plate is sleeved on the sliding rod, and the limiting plate is located on the side of the fixed base facing the splicing plate; the linkage plate is disposed at the end of the sliding rod away from the splicing plate, and the side wall of the linkage plate facing the splicing plate abuts against the fixed base; the locking block is slidably disposed on the side wall of the fixed base facing the splicing plate, and the side wall of the locking block facing the limiting plate has an insertion inclined surface to facilitate driving the limiting plate away from the fixed base, and the locking block is fitted between the limiting plate and the fixed base; the locking cylinder is disposed on the fixed base to drive the locking block closer to or away from the limiting plate.

[0021] By adopting the above technical solution, the locking cylinder drives the locking block to gradually insert into the gap between the limiting plate and the fixed seat through the insertion inclined surface. The locking block pushes the limiting plate away from the fixed seat, and the limiting plate drives the sliding rod and the linkage plate to move. When the locking block is inserted into the gap between the limiting plate and the fixed seat, the linkage plate abuts against the side wall of the fixed seat away from the splicing plate, the sliding rod is locked, and the corresponding splicing plate position is fixed. When the locking cylinder drives the locking block to retract, there is a gap between the limit plate and the fixed seat, causing the sliding rod to be in a sliding state. The corresponding splicing plate can be moved by the drive component to gradually move away from the wall panel body.

[0022] Preferably, the drive assembly includes a drive rod, a connecting frame, and a drive cylinder; the drive rod is slidably mounted on the fixed base along the height direction of the fixed base, and the end of the drive rod facing the linkage plate has a guide surface to facilitate the linkage plate moving away from the fixed base; the connecting frame is mounted on the drive rod, and the drive cylinder is mounted on the fixed base to drive the connecting frame to move the drive rod up and down.

[0023] By adopting the above technical solution, when the locking assembly releases the position lock on the sliding rod, the limiting plate, and the linkage plate, the drive cylinder drives the drive rod to move downward along the height direction of the fixed seat through the connecting frame. The guide surface of the drive rod passes through each layer of linkage plate from top to bottom. When the guide surface passes through the linkage plate, the guide surface pushes the linkage plate to move away from the fixed seat. The linkage plate drives the corresponding splicing plate to move towards the fixed seat through the sliding rod and the limiting plate, so that the splicing plate of that layer is separated from the outer wall of the wall panel body. This realizes that each layer of splicing plate is pulled back from top to bottom, realizing the separation of the layers from the wall panel body.

[0024] Preferably, the workbench is provided with several sets of waste holes, which extend and are distributed around all templates, and the bottom wall of the workbench is provided with a collection pipe for covering all the waste holes.

[0025] By adopting the above technical solution, the high-pressure water jet sprayed by the flushing component carries the stripped slurry debris down the outer wall of the template, and flows into the collection pipe through the waste hole for unified collection and discharge, keeping the surface of the workbench clean.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application uses a shock-absorbing component to apply uniform micro-vibration to loosen the wall panel body from the base plate, an inflatable component to inject high-pressure gas to form an air film to initially separate the template from the wall panel body, and a flushing component to flush along the joint with high pressure to achieve complete peeling. These three processes work together to replace the traditional manual knocking demolding, transforming the concentrated impact force into a uniformly distributed force, effectively reducing the demolding difficulty, avoiding damage to the wall panel surface, and improving demolding efficiency and product quality. By designing the template as multiple splicing panels that are sequentially spliced ​​along the height direction, and using locking and driving components to pull the splicing panels back layer by layer in sequence, the adhesive force of the entire template is decomposed into the adhesive force of a single splicing panel, which greatly reduces the peeling resistance and makes the demolding process more controllable and stable. By cooperating with the sealing screw, insertion hole, and air inlet in the inflation assembly, the sealing screw seals the channels during pouring to prevent slurry blockage and ensure the integrity of the wall panel surface. During demolding, the sealing screw moves outward so that the air inlet connects with the interior of the template through the insertion hole, ensuring the reliable realization of the inflation function. In addition, when the flushing assembly flushes the template and wall panel, the sealing screw seals the channels, reducing the phenomenon of water flow blocking the insertion hole and air inlet.

A force-equalizing plate 34 has corresponding holes and is slidably fitted onto all the anti-detachment guide rods 33. A reset member 36 is fitted onto the anti-detachment guide rods 33. Specifically, the reset member 36 is a compression spring, whose elastic force drives the force-equalizing plate 34 towards the fixed plate 31, ensuring that the side wall of the force-equalizing plate 34 away from the worktable 2 remains in contact with the fixed plate 31 under the elastic force of the reset member 36. A vibration rod 35 is fixed to the side wall of the force-equalizing plate 34 facing the worktable 2. The end of the vibration rod 35 penetrates the worktable 2 and extends upwards towards the bottom wall of the base plate 1, with a gap between the top of the vibration rod 35 and the base plate 1.

Each set of templates 11 is composed of multiple sets of splicing plates 110 spliced ​​sequentially along the height direction of the fixing seat 22, and adjacent splicing plates 110 are tightly fitted together. Each set of fixing seats 22 is equipped with a locking component 7 and a driving component 8.

[0047] Reference Figure 2 and Figure 5 The locking assembly 7 is used to limit the position of the splicing plate 110. The locking assembly 7 includes a sliding rod 71, a limiting plate 72, a linkage plate 73, a locking block 74, and a locking cylinder 75. The sliding rod 71 is slidably inserted into the fixed base 22. The end of the sliding rod 71 away from the fixed base 22 is fixedly connected to the splicing plate 110. Each splicing plate 110 corresponds to two sliding rods 71, which are located at both ends of the splicing plate 110 respectively.

In the locked state, the side wall of the linkage plate 73 facing the splicing plate 110 is in contact with the back of the fixing seat 22.

[0049] Reference Figure 2 and Figure 5 A locking cylinder 75 is fixedly mounted on a fixed base 22, and the extension and retraction direction of the output end of the locking cylinder 75 is parallel to the length direction of the limiting plate 72.

The locking blocks 74 are symmetrically distributed at both ends of the limiting plate 72, and are fixedly connected to the locking cylinder 75. An insertion inclined surface 741 is provided on the side wall of the locking block 74 facing the limiting plate 72, so that the locking block 74 can be inserted between the limiting plate 72 and the fixed base 22, and drive the limiting plate 72 to move the sliding rod 71 and the splicing plate 110 in a direction away from the fixed base 22. When the locking block 74 is inserted into the gap between the limiting plate 72 and the fixed base 22, the sliding rod 71 is in a locked state, thereby limiting the position of the splicing plate 110.

[0050] Reference Figure 2 and Figure 5The drive assembly 8 is used to drive the splicing plate 110 to move towards the fixed base 22. The drive assembly 8 includes a drive rod 81, a connecting frame 82, and a drive cylinder 83.

The drive plate is located on the side of all the linkage plates 73 away from the worktable 2, and the drive rod 81 is located on the side of the linkage plate 73 away from the splicing plate 110. A guide surface 811 is provided at the end of the drive rod 81 facing the linkage plate 73, and the guide surface 811 gradually slopes from top to bottom away from the linkage plate 73.

[0051] Reference Figure 2 and Figure 5 The connecting frame 82 is fixed on the drive rod 81, and the drive cylinder 83 is fixedly installed on the fixed base 22. Its output end is connected to the connecting frame 82, and the extension and retraction direction of the output end of the drive cylinder 83 is parallel to the height direction of the fixed base 22, so as to drive the connecting frame 82 to drive the drive rod 81 to move up and down.

[0052] The implementation principle of a prefabrication device for exterior wall panels in green buildings according to an embodiment of this application is as follows: After the wall panel body 10 is cast and solidified in the mold cavity, it enters the demolding process. First, the vibration shock absorber 32 is activated, generating high-frequency vibration force that acts on the fixed plate 31. The fixed plate 31 transmits the vibration to the uniform force plate 34. The uniform force plate 34 slides along the anti-detachment guide rod 33, evenly distributing the vibration energy to each vibration shock rod 35, causing the vibration shock rod 35 to strike the bottom plate 1. After each impact, the reset member 36 uses elasticity to move the uniform force plate 34 down to reset it, so that the vibration shock absorber 32 can drive the uniform force plate 34 to move up again, causing the ends of the vibration shock rods 35 to intermittently strike the bottom surface of the bottom plate 1. The vibration is transmitted through the bottom plate 1 to the wall panel body 10, causing loosening and micro-gaps between the bottom surface of the wall panel body 10 and the bottom plate 1.

[0053] After the wall panel body 10 is loosened by vibration, the inflation assembly 4 is activated; the adjusting electric cylinder 444 drives the sliding frame 442 to move, and the adjusting rack 443 drives the sealing screw 41 to rotate synchronously through each fixed toothed ring 441. The sealing screw 41 uniformly withdraws outward a set distance, so that the channel between the insertion hole 111 and the air inlet 112 is opened. The pressurizing pump 42 sends high-pressure gas into the air inlet 112 through the air supply pipe 43. The gas is blown from the inclined air inlet 112 port onto the bonding interface between the inner wall of the template 11 and the wall panel body 10. The high-pressure gas permeates along the interface gap, forming an air film that gradually separates the inner wall of the template 11 from the outer wall of the wall panel body 10.

[0054] After air pressure stripping, the movable frame 21 is slid along the workbench 2 to the top of the wall panel body 10. The positioning cylinder 62 drives the positioning plate 63 to descend, and the positioning plate 63 fits into the positioning rod 61 at the corresponding position, completing the positioning and locking of the movable frame 21.

[0055] The lifting mechanism 52 drives the lifting platform 51 to descend to near the top of the wall panel body 10. The rotating motor 54 drives the rotating arm 53 to rotate. The sliding block 56 at the end of the extension rod 55 slides along the guide ring groove 511. The elastic force of the elastic element 58 pushes the extension rod 55 outward, making the sliding block 56 tightly adhere to the groove wall of the guide ring groove 511. The spray gun 57 moves in a circular motion along the circumferential contour of the wall panel body 10. The spray gun 57 sprays high-pressure water at the joint between the template 11 and the wall panel body 10. The water seeps into the bonding interface along the joint to wash and peel it off.

[0056] During the rinsing process, the locking assembly 7 and the driving assembly 8 work together to peel off the template 11 in layers. The locking cylinder 75 drives the locking block 74 to slide out of the gap between the limiting plate 72 and the fixed seat 22, creating a gap between the limiting plate 72 and the fixed seat 22. The sliding rod 71 returns to a sliding state, and the locking of the uppermost splicing plate 110 is released. The driving cylinder 83 drives the driving rod 81 to descend through the connecting frame 82. When the guide surface 811 of the driving rod 81 passes the uppermost linkage plate 73, the guide surface 811 pushes the linkage plate 73 to move away from the fixed seat 22. The linkage plate 73, through the sliding rod 71 and the limiting plate 72, drives the uppermost splicing plate 110 to move towards the fixed seat 22. This layer of splicing plate 110 detaches from the outer wall of the wall panel body 10, so that the splicing plate 110 is separated from the wall panel body 10 from top to bottom.

[0057] After the splicing panel 110 separates from the wall panel body 10 from top to bottom, the joint between the lower splicing panel 110 and the wall panel body 10 is exposed. The spray gun 57 can directly wash the joint between the lower splicing panel 110 and the wall panel body 10, which improves the washing and disassembly effect of the spray gun 57 on all parts of the wall panel body 10 in the height direction, thereby improving the convenience and effectiveness of demolding the precast wall panel.

[0058] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
